How many days from August 29 2027 is September 19, 2027?

Exactly 21. The count starts the day after August 29, 2027 and ends on September 19, 2027, which is the convention almost every contract and deadline uses: the start date is day zero, not day one. Counting the start date as well would give September 18, 2027 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
